6 Claims.

This invention relates to improvements in nozzles for applying cooling fluid to the interior of bottles and other glass containers, particularly in treating such containers to effect tempering thereof. I

An object of the invention is to provide a nozzle of novel construction and form by which a cooling fluid can be applied effectively to the inher surface ofthe bottom of the container that is to be tempered, even though such area is cony siderably greater than the cross-sectional area of the inlet opening at the opposite end of the container.

A further object of the invention is to provide .a nozzle by which a cooling fluid may be applied within a bottle or similar container so as to effect adequate concentration of cooling medium at the inner angular orcorner portion of such container.

A further object of the'invention is to provide a nozzle which will afford efiective means for applying a cooling fluid topractically the entire area of the inner surface of the bottom of. the container according'to a predetermined pattern and also, if desired, to the inner surface of the side wall of the container according to another predetermined pattern.

A more specific object of the invention is to provide a nozzle having a fluid discharge end portion constructed to assume a form of sulficiently small lateral extent as measured from the longitudinal axial line of the nozzle to permit passage of such discharge end portion through a restricted inlet opening at the neck end of a bottle or other container to the interior of such container and thereafter to assume a form of substantially greater lateral extent.

Application of a coiling fluid medium to the inner surface of the bottom of a glass container, either uniformly throughout the entire area thereof or variably according to a predetermined pattern as may be desired, obviously is difficult of accomplishment, particularly if the container has a relatively small or restricted inlet opening at its opposite or neck end, as in the case of many bottles and other narrow neck articles of glassware. The discharge end of a cooling nozzle must pass through such a relatively small or restricted opening to reach an effective or the most effective operating position within the container and this requirement tends to restrict or limit the area of bottom surface to which cooling fluid from the nozzle can be applied uniformly or according to a desired pattern.

I obviate or greatly reduce the afore-mentioned' difficulty by providing, according to one form of the present invention, a rotary nozzle having a fluid discharge end section or elongate shoe pivotally connected with the body of the nozzle so as to assume a position substantially in line with such body for passage through the relatively small or restricted inlet opening of the contain er and also capable of swinging angularly away from the axial line of the nozzle body to provide a laterally extending discharge member for the portion of the nozzle body that is located within the container. The pivotally connected end section or shoe may tend to assume its inactive position in line with the nozzle body by gravity and may be swung upwardly and outwardly to its operating or active position within the container by centrifugal force occasionedby the rotation of the nozzle about the longitudinal axis of its body portion or by back pressure exerted on the pivoted discharge end portion or shoe by the cooling fluid discharging-therefrom under pressure or by a combination of these forces. Obviously, theswingable discharge end section or shoe may be provided with suitable mechanical means for controlling its swinging movements between its inactive and active positions as above mentioned.

It is within the purview of the present invention that the discharge end section or foot may be rigidly connected with or secured in a laterally extending angular relation with the body of the nozzle. The extent of lateral projection from the nozzle body of such end section or shoe then will be limited to such a projection as-will not prevent passage of the portion of the nozzle body having the laterally projecting section or shoe thereon through the opening at one end of the container to and from an operating position within the container.

A nozzle embodying the invention is shown in operating position in a bottle in the accompanying drawing in which:

The view is a longitudinal vertical section through the bottle and through a'portion of the nozzle and certain associate bottle engaging elements, portions of the nozzle being broken away and omitted and the portion of the nozzle body that extends through the bottle neck being shown in side elevation.

Referring now to the drawing, the nozzle has a substantially straight and rigid body I which is adapted to extend through the neck portion 2 of the bottle 3 to dispose the free end of such ameter than the interior of the bottle neck 2 so that a narrow annular space 5 is provided between these parts.

The nozzle body I is provided at its free end with a discharge end section or hollow foot 6.

-When at the, operating position shown in the drawing, the member 6 extends from the axial line of the nozzle body considerably farther than the distance from such line to the inner wall of the neck portion of the bottle. To permit insertion of the nozzle into the bottle, the member 6 is pivotally connected at its inner end, as by the transverse pivot member I, to a partially cut away end portion 8 of the nozzle body. The interior Bu of the member 6, which is closed at its outer or free end, communicates with and Serves as a lateral extension of a longitudinally extending passage 9 in the nozzle body I when the member 6 is in its laterally projected position, as shown.

A suitable cooling fluid medium under pressure may pass through the passage 9, as indicated by the arrows at ID in the drawing, to the interior of the member 6 from which such cooling medium will be discharged through orifices I I in the then bottom or lower wall of the member 6 in jets which may be directed against the inner surface of the bottle bottom 4 as shown by the arrows in the drawing.

The connection of the member 6 with the body I, as just described, may be such that gravity will tend to swing the meniber 6 downwardly from its laterally projected operating position to a position substantially in line with a portion of the body I. This position of the member 6 permits ready insertion of the discharge end portion of the nozzle into the bottle and withdrawal therefrom. When in the bottle, the member 6 may be swung to and maintained in its projected operating position, as shown, by centrifugal force occasioned by the rotation of the nozzle about the axis of the body I or by back pressure from the discharging cooling fluid medium or by both these forces. The extent of upward swinging movement of the member 6 may be limited by the contact of a portion of such member with the upper edge of the partially cut away portion 8 of the nozzle body I.

The nozzle body I also may have a series of vertically spaced discharge orifices, such as indicated at I2, in the side wall thereof for directing jets of cooling medium from the passage 9 toward the inner longitudinal wall of the bottle. Also, a longitudinally extending exhaust passage I3 may be provided in the nozzle body I. As shown, the exhaust passage I3 is open at the bottom or free end of the nozzle body and also may be provided at intervals with exhaust ports I4. These exhaust ports may be located in the side of the body I opposite to that which is provided with the discharge ports I3 and at diiferent levels.

In practice, the nozzle may be supported and operated by any suitable supporting and operating mechanism, one example of which is disclosed in the application of Thomas D. Green for Method of and apparatus for handling and tempering glassware, Serial No. 306,085, filed concurrently herewith. Such apparatus affords facilities for detachably holding the bottle or other article that is to be cooled in a predetermined desirable relation with the nozzle, for effecting relative axial movements of the bottle and the nozzle for proper positioning of the nozzle in the bottle and withdrawal therefrom, and for rotating the nozzle about its own axis and/or the bottle about its axis during the use of the nozzle to apply a cooling fluid medium to the interior of the bottle. Such apparatus includes tongs, represented on the present drawing by the fragmentarily shown tong members I5, and a clamping or latching plate IS in contact with the upper edge of the bottle and cooperative with the tongs to retain the bottle and the nozzle firmly in their proper relative positions while permitting relative rotary motion between them, as by rotation of the nozzle about its own vertical axis.

The drawing shows a simple form of structure for rotatably supporting the nozzle body I and for rotating such body about its longitudinal axis. As shown, the body I is journaled in a horizontal bearing portion ll of a support I8. A collar I9 may be secured on the body I to rest upon such bearing portion of the support to prevent downward axial movement of the body I relative to the support I8. The latter may have a vertical bearing portion 20 in which a short shaft 2! is journaled. The shaft 2| is provided at one end with a manually operable crank 22 and at its other end with a bevel gear 23 in mesh with a bevel gear 24 on the body I.

The discharge orifices II in the member 6 and the discharge orifices I2 in the body portion of the nozzle are suitably located and are of suitable sizes to produce the desired internal cooling or chilling of the bottom and longitudinal walls of the bottle when a cooling fluid medium,

such as air under pressure, is discharged through these orifices and the nozzle is rotated about its own longitudinal axis to cause the discharged jets and currents of cooling fluid medium thoroughly and completely to scrub the inner surfaces of the bottom and longitudinal walls of the bottle. The cooling fluid so applied, after contacting with and abstracting heat from the glass surfaces at the interior of the bottle, may be removed from the bottle through the exhaust passage l3 or mainly through the exhaust passage I3 and in part through the space 5 between the bottle neck and the-body of the nozzle.

The size, number, relative arrangement and directions of the cooling fluid discharge orifices and exhaust orifices may be varied according to differing requirements of diiferent services in which nozzles of the present invention may be employed. The degree of angularity of the member 6 with the nozzle body may be greater or less than that shown when the member 6 is in its laterally projecting, active position. Other changes in and modifications of the form and structure of the device shown in the drawing may be made as individual preferences or service requirements dictate or make desirable.
